Let's stop messing with the page refcount, and use a flag that is set / cleared atomically to remember whether a vsie page is currently in use. Note that we could use a page flag, or a lower bit of the scb_gpa. Let's keep it simple for now, we have sufficient space. While at it, stop passing "struct kvm *" to put_vsie_page(), it's unused.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
